Anyone out there that's placed a parent in a Board & Care facility?

We are looking at B & C for Mom because it is at a home with just 6 clients and 2 caregivers per shift. Less expensive than a NH and care is more personal. Seems to have a homey atmosphere. The owner is an RN, has 6 homes in nice areas.
Was just wondering if any others have had any experiences or advice on what I should be checking for when I visit.
